Virtual currency secured physical currency transmission system

ABSTRACT

Virtual currency ledger secured physical currency transmissions include receiving a physical currency transfer request from a physical currency receiver device of a physical currency receiver, and identifying a physical currency deliverer device of a physical currency deliverer. A physical currency delivery confirmation code is then associated with a recipient identified in the physical currency transfer request, and a virtual currency address controlled by the physical currency deliverer and included in a virtual currency public ledger is identified to the physical currency receiver device. A reimbursement request code is then received from the physical currency deliverer device and verified using the physical currency delivery confirmation code. In response to the verification, a multi-signature transaction that has been previously signed by the physical currency receiver is then signed to cause a virtual currency amount to be transferred via the virtual currency public ledger to the virtual currency address controlled by the physical currency deliverer.

BACKGROUND Field of the Disclosure

The present disclosure generally relates to physical currency transmission, and more particularly to a physical currency transmission system that is secured using a virtual currency.

Related Art

While innovations in electronic money transfer technology have made the transfer of money between parties quicker and easier, such electronic money transaction technology is not yet universally available. As such, many people still rely on the transfer of physical currency (e.g., cash). For example, laborers in many parts of the world earn physical currency from their employers, and may wish to send that physical currency to relatives in a different location. In such situations, those laborers must use trust-based systems in which they provide an amount of the physical currency to a first money transfer agent in a first location that has agreements with second money transfer agent(s) in a second location, and then trust the first money transfer agent and the second money transfer agent to cause the amount of the physical currency to be delivered to their relatives in the second location. As such, conventional physical currency transmission systems are unsecured and suffer from the need to trust money transfer agents, with little or no recourse if a desired amount of physical currency trusted to money transfer agents is not delivered to an intended recipient.

Thus, there is a need for a secured physical currency transmission system.

DETAILED DESCRIPTION

Embodiments of the present disclosure include systems and methods for securing physical currency transmission using a virtual currency. As discussed above, conventional physical currency transmission systems are unsecured and suffer from the need to trust money transfer agents, with little or no recourse if a desired amount of physical currency trusted to money transfer agents is not delivered to an intended recipient. Embodiments of the systems and methods of the present disclosure reduce the need for trust in physical currency transmission by, for example, using a virtual currency public ledger to verify the identity of physical currency transfer agents, as well as using a multi-signature transaction that is configured to transfer virtual currency on the virtual currency public ledger to reimburse a physical currency transfer agent who delivers physical currency to a recipient when that physical currency is confirmed as having been delivered.

As discussed below, a physical currency transfer request that identifies a physical currency amount and physical currency recipient information may be received from a physical currency receiver, and a physical currency deliverer may then be identified. In some examples, either or both of the physical currency recipient and the physical currency deliverer may then be verified/authenticated using a virtual currency public ledger. A physical currency delivery confirmation code may then be associated with a recipient identified in the physical currency recipient information, and a virtual currency address that is controlled by the physical currency deliverer and that is included in the virtual currency public ledger may be identified as well. When a reimbursement request code is received from the physical currency deliverer, it may be verified using the physical currency delivery confirmation code and, in response to the verification, a multi-signature transaction that has been previously signed by the physical currency receiver is signed to cause a virtual currency amount to be transferred via the virtual currency public ledger to the virtual currency address that is controlled by the physical currency deliverer. As such, physical currency receivers and physical currency deliverers may be verified using a virtual currency public ledger, and reimbursements for physical currency delivered to a recipient by the physical currency deliverer may be made via a multi-signature transaction that transfers virtual currency to the physical currency deliverer only when a physical currency delivery confirmation code is provided to the physical currency deliverer by the recipient, thus securing the physical currency transmission using the virtual currency.

Referring now to FIGS. 1, 2, and 3, a method 100 for transmitting physical currency is illustrated. In some embodiments of the method 100 described below, one or more system provider devices may operate to perform or enable the method 100. For example, a system provider may utilize system provider device(s) to enable the transfer of physical currency between a sender and a recipient using either or both of a physical currency receiver and a physical currency deliverer. In a specific example, a payment service provider such as, for example, PayPal, Inc. of San Jose, Calif., may act as the system provider and utilize a payment service provider device as the system provider device discussed below to perform the method 100, and in some embodiments may operate in cooperation with one or more other system providers (via their system provider devices) and/or users (via their user devices) to perform the method 100. However, these embodiments are meant to be merely exemplary, and one of skill in the art in possession of the present disclosure will recognize that a wide variety of system providers and users may operate, alone or together, to provide the systems and methods discussed herein without departing from the scope of the present disclosure.

Referring now to FIG. 2, an embodiment of an electronic coin 200 that may provide the transfers of the virtual currency discussed below is illustrated and described briefly for reference in the discussion below. In those embodiments, a virtual currency system associated with the present disclosure may define an electronic coin as a chain of digital signatures provided by previous owners of the electronic coin to subsequent owners of the electronic coin. In the illustrated embodiment, the electronic coin 200 is owned by an owner 202, and FIG. 2 illustrates how the electronic coin 200 is defined by the digital signatures of the previous owners 204, 206, and 208. Specifically, in transaction A, a hash of the public key of owner 206 (i.e., the owner receiving, as a result of transaction A, an electronic coin 200 ₁ defined by digital signatures provided up to transaction A) and the previous transaction (not illustrated, but occurring prior to transaction A) was signed by owner 208 (i.e., the owner providing, as a result of transaction A, the electronic coin 200 ₁ defined by digital signatures provided up to transaction A) using a private key and added to an initial electronic coin (which was defined by digital signatures provided up to the transaction prior to transaction A) such that the electronic coin 200 ₁ was transferred to owner 206.

Similarly, in transaction B, a hash of the public key of owner 204 (i.e., the owner receiving, as a result of transaction B, an electronic coin 200 ₂ defined by digital signatures provided up to transaction B) and transaction A was signed by owner 206 using a private key and added to the electronic coin 200 ₁ such that the electronic coin 200 ₂ was transferred to owner 204. Similarly, in transaction C, a hash of the public key of owner 202 (i.e., the owner receiving, as a result of transaction C, the electronic coin 200 defined by digital signatures provided up to transaction C) and the transaction B was signed by owner 204 using a private key and added to the electronic coin 200 ₂ such that the electronic coin 200 was transferred to owner 202. As is understood in the art, any user receiving an electronic coin (e.g., owner 206 in transaction A, owner 204 in transaction B, and owner 202 in transaction C) can verify the signatures to verify the chain of ownership of the electronic coin. In the discussion below, it should be understood that the term “electronic coin(s)” may be used to encompass any amount or type of electronic coins.

Referring now to FIG. 3, an embodiment of a virtual currency public ledger 300 is illustrated and described briefly for reference in the discussion below. As discussed above, the virtual currency public ledger 300 operates to verify that users transferring an electronic coin (e.g., referring back to FIG. 2, owner 206 in transaction A, owner 204 in transaction B, and owner 202 in transaction C) did not “double-spend” (e.g., use a private key to sign any previous transactions involving) that electronic coin. To produce the virtual currency public ledger 300, a distributed network of devices operate to agree on a single history of transactions in the order in which they were received such that it may be determined that a transaction between users using an electronic coin is the first transaction associated with that electronic coin. Each device in the distributed network operates to collect new transactions into a block, and then to increment a proof-of work system that includes determining a value that when hashed with the block provides a required number of zero bits.

For example, for a block 302 that includes a plurality of transactions 302 a, 302 b, and up to 302 c, a device in the distributed network may increment a nonce in the block 302 until a value is found that gives a hash of the block 302 the required number of zero bits. The device may then “chain” the block 302 to the previous block 304 (which may have been “chained” to a previous block, not illustrated, in the same manner). When devices in the distributed network find the proof-of-work for a block, that block (e.g., block 302) is broadcast to the distributed network, and other devices in the distributed network will accept that block if all the transactions in it are valid and not already spent (which may be determined by creating the next block using the hash of the accepted block 302). The distributed network will always consider the longest chain of blocks to be the correct one, and will operate to continue to extend it. If a device receives two different versions of a block, it will work on the first block received, but save the second block received in case the branch of the chain that includes the second block becomes longer (at which point that device with switch to working on the branch of the chain that includes the second block). The electronic coin(s) 200 and virtual currency public ledger 300 discussed above provide a distributed virtual currency system in which users may participate in transactions with each other without the need for a centralized authority such as a bank. Each of those transactions is recorded in the virtual currency public ledger 300 to ensure that the electronic coins may only be spent by a user once.

Referring now to FIG. 4, an embodiment of a physical currency transmission system 400 is illustrated and described briefly for reference in the method 100 discussed below. The physical currency transmission system 400 includes one or more system provider device(s) 402 that are coupled to a network 404. In the illustrated embodiment, one or more physical currency receiver device(s) 406 are coupled to the network 404 and, as discussed below, may be associated with respective physical currency receivers that may receive physical currency from a sender 408. However, as also discussed below, in some embodiments the physical currency receiver device 406 may be replaced by a sender device that is controlled by the sender 408. In the illustrated embodiment, one or more physical currency deliverer device(s) 410 are coupled to the network 404 and, as discussed below, may be associated with respective physical currency deliverer that may deliver physical currency to a recipient 412. In the illustrated embodiment, the physical currency transmission system 400 also includes public ledger device(s) 414 that are coupled to a transactional database 416 and the network 404. As discussed above, the public ledger device(s) 414 may operate to receive virtual currency transactions broadcast by any of the devices, confirm those transactions, and generate a public ledger 418 as discussed above with reference to FIG. 3.

Referring now to FIG. 5, an embodiment of a device 500 is illustrated that in different embodiments may be sender device, the physical currency receiver device, the physical currency deliverer device, and/or the system provider device discussed herein. As such, in some examples (e.g., those where the device 500 is controlled the system provider device(s) 402), the device 500 may be provided by one or more server devices, while in other examples (e.g., those where the device 500 is controlled by the sender, the physical currency receiver, or the physical currency deliverer), the device 500 may be provided by a desktop computing system, a laptop/notebook computing system, a tablet computing system, a mobile phone, and/or other user devices known in the art. However, one of skill in the art in possession of the present disclosure will recognize that the device 500 may be provided by any of a variety of computing device in the different examples discussed below.

In the illustrated embodiment, the device 500 includes a chassis 502 that houses the components of the device 500, only some of which are illustrated in FIG. 5. For example, the chassis 502 may house a processing system (not illustrated) and a non-transitory memory system (not illustrated) that includes instructions that, when executed by the processing system, cause the processing system to provide a wallet engine 504 that is configured to perform the virtual currency transaction and transfer functionality discussed below. The chassis 502 may also house a communication system 506 that is coupled to the wallet engine 504 (e.g., via a coupling between the communication system 506 and the processing system) and configured to provide for communication through the network 404 as detailed below. In the illustrated embodiment, device 500 also includes a storage device with a wallet database 508 having private key(s) 508 a that are configured to provide the virtual currency transfers discussed below. While the device is illustrated as including a chassis 502 that houses the wallet database 508, one of skill in the art in possession of the present disclosure will recognize that the wallet database may be provided in a different device/chassis than the device 500 such as, for example, a network attached storage device, a non-network attached computing device (e.g., a “cold storage” device), and/or any other device or storage system known in the art.

Referring now to FIGS. 6 and 7, embodiments of physical currency transmission systems 600 and 700, respectively, are illustrated. The physical currency transmission systems 600 and 700 illustrate different embodiments of the physical currency transmission system of the present disclosure that depend on the access of a sender of physical currency to a sender device that may communicate with the system provider device(s) as discussed below. Furthermore, as discussed below, each of the embodiments of the physical currency transmission systems 600 and 700 may include multiple different embodiments in which any of the sender, the physical currency receiver, and/or the physical currency deliverer has a verified account with the system provider. As such, in some examples the sender or physical currency receiver has an account with the system provider and the physical currency deliverer does not have an account with the system provider, in some examples the sender or physical currency receiver do not have an account with the system provider and the physical currency deliverer has an account with the system provider, in some examples both of the sender or physical currency receiver and the physical currency deliverer have an account with the system provider, and in some examples neither of the sender or physical currency receiver and the physical currency deliverer has an account with the system provider.

FIG. 6 illustrates the embodiment of the physical currency transmission system 600 that includes a physical currency receiver device 602 of a physical currency receiver that may receive physical currency from a sender during the method 100. The physical currency receiver device 602 is configured to communicate with a system provider device 606, and the system provider device 606 is configured to communicate with a physical currency deliverer device 608 of a physical currency deliverer that may deliver physical currency to a recipient 610. As discussed below, the embodiment of the physical currency transmission system 600 may be utilized when the sender 604 does not have access to a device that would enable them to communicate with the system provider (via the system provider device 606), and instead utilizes the physical currency receiver (who has access to a physical currency receiver device 602 that enables them to communicate with the system provider) to transmit physical currency to the recipient 610.

FIG. 7 illustrates the embodiment of the physical currency transmission system 700 that includes a sender device 702 of a sender that is configured to communicate with a system provider device 704, and the system provider device 704 is configured to communicate with a physical currency deliverer device 706 of a physical currency deliverer that may deliver physical currency to a recipient 708. As discussed below, the embodiment of the physical currency transmission system 700 may be utilized when a sender has access to the sender device 702 that enables them to communicate with the system provider (via the system provider device 606) to transmit physical currency to the recipient 610. While a few examples have been provided, one of skill in the art in possession of the present disclosure will recognize that other modifications to the physical currency transmission system will fall within the scope of the present disclosure as well.

Referring back to FIG. 1, the method 100 begins at block 102 where a physical currency transfer request is received from a sender or physical currency receiver. In an embodiment, the system provider device(s) 402 receives a physical currency transfer request through the network 404 from one of the physical currency receiver device(s) 406. As discussed above, in the embodiment of the physical currency transmission system 600, the physical currency receiver device 602 may be controlled by a physical currency receiver that is separate from the sender 604, while in the embodiment of the physical currency transmission system 700, the sender device 702 is controlled by a sender.

As such, in an example of the physical currency transmission system 600, at block 102 the sender may provide an amount of a first physical currency (e.g., $500 United States dollars) to the physical currency receiver, and identify to the physical currency receiver a currency type for the delivered physical currency, the recipient 610, a recipient location, and/or any other information that could be utilized during the method 100 discussed below. In response, the physical currency receiver may use the physical currency receiver device 602 to send the physical currency transfer request to the system provider device 606 that includes the amount of the first physical currency, the currency type for the delivered physical currency, the identity of the recipient 610, the recipient location, and/or any other information that could be utilized during the method 100. In an example of the physical currency transmission system 700, at block 102 the sender may use the sender device 702 to send the physical currency transfer request to the system provider device 704 that includes an amount of a first physical currency, a currency type for the delivered physical currency, the identity the recipient 708, a recipient location, and/or any other information that could be utilized during the method 100 discussed below.

Referring now to FIG. 8, an embodiment of a device 800 that may be the physical currency receiver device or the sender device discussed above is illustrated. The device 800 includes a display screen 802 displaying an embodiment of a physical currency transfer request screen 804 that may be provided to the user of the device 800 in order to allow that user to provide the physical currency transfer request to the system provider at block 102. In the illustrated example, the physical currency transfer request screen 804 includes a recipient information section 806 that allows a user to provide a physical currency amount/type, a delivered physical currency type, a recipient name, and a recipient location. In embodiments in which the device 800 is a physical currency receiver device controlled by a physical currency receiver, the information provided in the recipient information section 806 by the physical currency receiver may be received by the physical currency receiver from the sender. For example, the sender may provide an amount of physical currency, and may identify the delivered physical currency type, the recipient, and the recipient location, to the physical currency receiver. The physical currency receiver may then provide that information using the physical currency transfer request screen 804 and send the physical currency transfer request to the system provider at block 102. In embodiments in which the device 800 is a sender device controlled by the sender, the information may be provided in the recipient information section 806 by the sender.

In some embodiments, the sender may select a physical currency receiver for performing the method 100. Referring now to FIG. 9, an embodiment of a sender device 900 is illustrated. The sender device 900 includes a display screen 902 displaying an embodiment of a physical currency receiver selection screen 904 that may be provided to a sender to select a physical currency receiver. In the illustrated example, the physical currency receiver selection screen 904 includes a map 906 that provides map details about a location of the sender, along with identifiers 906 a, 906 b, and 906 b for physical currency receivers available at the location of the sender, and a physical currency receiver section 908 that includes details about each of the physical currency receivers associated with the respective identifiers 906 a-c on the map 906.

In one example, a sender wishing to send physical currency to a recipient may use the physical currency transfer request screen 804 to identify the amount of physical currency, the delivered physical currency type, the recipient, and the recipient location to the system provider device 402 in a physical transfer request. The system provider device 402 may then publish some or all of the details of the physical transfer request (e.g., at least the amount of the physical currency and the location) in a physical currency receiver solicitation to a network of the physical currency receiver devices 406. In response to the physical currency receiver solicitation, physical currency receivers may use their respective physical currency receiver devices to “bid” on receiving the physical currency from the sender by, for example, identifying a fee associated with receiving the physical currency from the sender.

In response to receiving those bids, the system provider device 402 may provide the physical currency receiver selection screen 904 over the network for display on the sender device 900 that includes physical currency receivers, their associated fees, and in the illustrated embodiment, ratings that were previously collected by the system provider and that are based on other senders that used those physical currency receivers previously. As such, in embodiments of block 102 where the sender has a sender device for sending physical currency transfer requests to the system provider, the sender may use the physical currency receiver selection screen 904 to select a physical currency receiver for performing the method 100. However, in other embodiments, the system provider may provide the physical currency receiver options from a database of physical currency receivers (e.g., rather than a bid process), and/or operate to select the physical currency receiver for performing the method 100 (e.g., without input from the sender) based on, for example, the fees charged by that physical currency receiver, the ratings for that physical currency receiver, and/or any other information that would be apparent to one of skill in the art in possession of the present disclosure.

The method 100 then proceeds to block 104 where a physical currency deliverer is identified. In an embodiment, at block 104 the system provider device 402 identifies a physical currency deliverer. For example, in response to receiving the physical currency transfer request that identifies the amount of physical currency, the delivered physical currency type, the recipient, and the recipient location, the system provider device 402 may then publish some or all of the details of the physical transfer request (e.g., at least the amount of the physical currency and the location) in a physical currency deliverer solicitation to a network of the physical currency deliverer devices 410. In response to the physical currency deliverer solicitation, physical currency deliverers may use their respective physical currency deliverer devices to “bid” on delivering the physical currency to the recipient (or recipient location) by, for example, providing a fee associated with receiving the physical currency from the sender. The system provider may then select one of those physical currency deliverers for delivering the physical currency to the recipient.

Referring now to FIG. 10, an embodiment of a device 1000 that may be the sender device or the physical currency receiver device discussed above is illustrated. The device 1000 includes a display screen 1002 displaying an embodiment of a physical currency deliverer selection screen 1004 that may be provided to a sender or a physical currency receiver to select a physical currency deliverer. In the illustrated example, the physical currency deliverer selection screen 1004 includes a map 1006 that provides map details about the recipient location to which the physical currency is to be delivered, along with identifiers 1006 a, 1006 b, and 1006 b for physical currency deliverers available at the recipient location, and a physical currency deliverer section 1008 that includes details about each of the physical currency deliverers associated with the respective identifiers 1006 a-c on the map 1006.

In one example, in response to receiving bids from the physical currency deliverers, the system provider device 402 may provide the physical currency deliverer selection screen 1004 over the network for display on the device 1000 that includes physical currency deliverers, their associated fees, and in the illustrated embodiment, ratings that were previously collected by the system provider and that are based on other senders and/or physical currency receivers that previously used those physical currency deliverers to deliver currency to recipients. As such, in embodiments of block 104, the sender or the physical currency receiver may use the physical currency deliverer selection screen 1004 to select a physical currency deliverer for performing the method 100. In response to that selection, the system provider may identify the selected physical currency deliverer at block 104. However, in other embodiments, the system provider may select the physical currency deliverer for performing the method 100 from a database of physical currency deliverers based on, for example, the fees charged by that physical currency deliverer, the ratings for that physical currency deliverer, and/or any other information that would be apparent to one of skill in the art in possession of the present disclosure.

In some embodiments, following block 102 and/or block 104, the identity of the sender, the physical currency receiver, and/or the physical currency deliverer may be verified. In some examples, the sender may include an account with the system provider such as, for example, a payment account with a payment provider that operates as the system provider, and thus may be verified following block 102 using authentication credentials or other verification methods known in the art. Similarly, the physical currency receiver include an account with the system provider such as, for example, a payment account with a payment provider that operates as the system provider, and thus may be verified following block 102 using authentication credentials or other verification methods known in the art. Similarly, in some examples, the physical currency deliverer may include an account with the system provider such as, for example, a payment account with a payment provider that operates as the system provider, and thus may be verified following block 102 using authentication credentials or other verification methods known in the art.

In other embodiments, any of the sender, the physical currency receiver, and/or the physical currency deliverer may not have a payment account (or other account) with the system provider. In such situations, the identity of any of those parties may be verified using a virtual currency public ledger. For example, a co-inventor of the present disclosure created a virtual currency public ledger authentication system that is described in U.S. patent application Ser. No. 15/098,079, attorney docket number 70481.2080US01, filed on Apr. 13, 2016, the disclosure of which is incorporated by reference in its entirety.

As described in that patent application, a virtual currency public ledger authentication system may include a registration method in which each of a user and a system provider perform a common hash operation on user identification information (e.g., a user name, a user address, a user phone number, a user date of birth, a user social security number, etc.) to generate respective first and second static user keys. The system provider then identifies a first registration public ledger address to the user, the user identifies a second registration public ledger address to the system provider, and the user then subsequently sends the first static user key to the first registration ledger address from the second registration public ledger address in a transaction in the virtual currency public ledger. The system provider then accesses that registration ledger address via the public ledger (using the identifications of the first and second registration ledger addresses to reference the public ledger) to retrieve the first static user key and register the user with the system if the first static user key matches the second static user key generated by the system provider. The first static user key in the public ledger then becomes a verified static user key in the public ledger that may be used for subsequent authentication of the user, and the system provider may erase or otherwise discard the user identification information and the second static user key.

Following registration, the user may authenticate with the system provider in an authentication method by sending the system provider a first previous authentication public ledger address that was used in a previous authentication attempt and a first current authentication public ledger address for use in the current authentication attempt. The system provider uses the first previous authentication public ledger address to access a database that identifies previous authentication public ledger addresses used by the user in previous authentication attempts and allows for the determination of a number of previous authentication attempts by the user, and identify the verified static user key in the public ledger. The system provider then performs a hash operation using the number of previous authentication attempts and the verified static user key to generate a first user authentication key. The system provider then provides the user a second current authentication public ledger address for use in the current authentication attempt. The user may also perform the hash operation using the number of previous authentication attempts and the verified static user key (both of which may be stored by the user in a transaction wallet) to generate a second user authentication key, and send the second user authentication key from the first current authentication public ledger address to the second current authentication public ledger address in a transaction on the public ledger. The system provider may then check the transaction sent from the first current authentication public ledger address to the second current authentication public ledger address in the public ledger to retrieve the second user authentication key and authenticate the user with the system if the second user authentication key matches the first user authentication key generated by the system provider.

Thus, senders, physical currency receivers, and/or physical currency deliverers may participate in the method 100 whether or not they have an account with the system provider. As such, physical currency receiver solicitations and/or physical currency deliverer solicitations may be responded to by both physical currency receivers and/or physical currency deliverers that have accounts with the system provider, as well as physical currency receivers and/or physical currency deliverers that do not have accounts with the system provider, as those with accounts may be verified via information associated with their respective accounts, and those without accounts may be verified via a virtual currency public ledger. One of skill in the art in possession of the present disclosure will recognize that the ability to verify physical currency receivers and/or physical currency deliverers in such a manner allows bids on physical currency receiver solicitations and/or physical currency deliverer solicitations from any of those parties to be accepted with the knowledge that those parties are verified entities. For example, a sender may select a physical currency receiver and a physical currency deliverer for use in transmitting physical currency to the recipient with the knowledge that they have been verified by the system provider. Similarly, a physical currency receiver may select a physical currency deliverer for use in transmitting physical currency to the recipient with the knowledge that the physical currency deliverer has been verified by the system provider, and a physical currency deliverer may accept a physical currency deliverer solicitation with the knowledge that the physical currency receiver or the sender have been verified by the system provider.

The method 100 then proceeds to block 106 where a physical currency delivery confirmation code is generated and associated with a recipient. In an embodiment, the system provider device(s) 402 may operate at block 106 to generate a physical currency delivery confirmation code and associate that physical currency delivery confirmation code with the recipient 412. For example, at block 106, the system provider device(s) 402 may generate a numerical code, an alphanumeric code, a word or phrase, and/or any codes having any other code characteristics known in the art. In a specific example, the system provider device(s) 402 may send a request over the network 404 to the physical currency receiver device 406 or the sender device from which the physical currency transfer request was received, and the physical currency receiver or the sender, respectively, may transmit a request to the system provider device to generate and associate a desired physical currency delivery confirmation code with the recipient 412 at block 106. As such, in some embodiments the sender 408 may suggest the details of the physical currency delivery confirmation code to the system provider device 402 (e.g., via their sender device) so that the system provider may generate the physical currency delivery confirmation code, while in the some embodiments the physical currency receiver may solicit the sender 408 for the details of the physical currency delivery confirmation code, and provide those details to the system provider device 402 (e.g., via their physical currency receiver device 406) so that the system provider may generate the physical currency delivery confirmation code, or may simply suggest the details for the physical currency delivery confirmation code (i.e., without soliciting the sender 408 for those details) to the system provider device 402 (e.g., via their physical currency receiver device 406) so that the system provider may generate the physical currency delivery confirmation code. While a few examples have been provided, one of skill in the art in possession of the present disclosure will recognize that a variety of code generation techniques may be utilized to generate the so that the system provider may generate the physical currency delivery confirmation code that is associated with the recipient 412 at block 106.

At block 106, the physical currency delivery confirmation code ‘that is generated and associated with the recipient 412 is also provided to the recipient 412. In one example, the system provider device(s) 402 may transmit the physical currency delivery confirmation code to the recipient 412 via recipient contact information (e.g., an email address, a phone number (e.g., a call or text), a social media identifier, a physical address, etc.) that may be provided by the sender or the physical currency transfer receiver using, for example, the physical currency transfer request screen 804. In another example, the sender or the physical currency receiver may transmit the physical currency delivery confirmation code (the details of which may have been determined by the sender or the physical currency receiver) to the recipient 412 via recipient contact information (e.g., an email address, a phone number (e.g., a call or text), a social media identifier, a physical address, etc.) which may be known to the sender, or provided by the sender to the physical currency transfer receiver using, for example, the physical currency transfer request screen 804. While a few examples have been provided, one of skill in the art in possession of the present disclosure will recognize that the physical currency delivery confirmation code generated at block 106 may be provided to the recipient 412 using a variety of techniques.

The method 100 then proceeds to block 108 where a virtual currency address that is controlled by the physical currency deliverer is identified to the sender or physical currency receiver. In an embodiment, the system provider device(s) 402 may operate at block 108 to identify, to the physical currency receiver, a virtual currency address that is controlled by the physical currency deliverer. For example, at block 108 the system provider device(s) 402 may send a virtual currency address request through the network to the physical currency deliverer device 410 of the physical currency deliverer that accepted the physical currency deliverer solicitation, and the physical currency deliverer may respond to the virtual currency address request using the physical currency deliverer device 410 to send a virtual currency address that is controlled by the physical currency deliverer (e.g., that is generated by an electronic wallet provided in the physical currency deliverer device and that includes private key(s) that are configured to transfer electronic coins from that virtual currency address to another virtual currency address) through the network to the system provider device(s) 402. In response to receiving that virtual currency address, the system provider device(s) 402 may identify that virtual currency address to the physical currency receiver device 406 or the sender device via an email, a text message, a phone call, a web page, an application page, and/or any other virtual currency address notification technique that would be apparent to one of skill in the art in possession of the present disclosure.

In another example, at block 108 the physical currency receiver device 406 or the sender device may send the virtual currency address request through the network to the physical currency deliverer device 410 of the physical currency deliverer that accepted the physical currency deliverer solicitation, and the physical currency deliverer may respond to the virtual currency address request by using the physical currency deliverer device 410 to send a virtual currency address that is controlled by the physical currency deliverer (e.g., that is generated by an electronic wallet of the physical currency deliverer that includes private key(s) that are configured to transfer electronic coins from that virtual currency address to another virtual currency address) through the network to the physical currency receiver device 406 or the sender device. While a few examples have been provided, one of skill in the art in possession of the present disclosure will recognize that the virtual currency address may be identified to the physical currency receiver or sender in a variety of manners while remaining within the scope of the present disclosure. For example, rather than providing the virtual currency address in response to a virtual currency address solicitation, the physical currency deliverer may provide the virtual currency address as part of the “bid” that is provided in response to the physical currency deliverer solicitation.

In some embodiments, subsequent to identifying the virtual currency address to the physical currency receiver, the system provider device(s) 402 may receive information for signing a multi-signature transaction through the network 404 from the physical currency receiver device 406 or the sender device. For example, upon receiving the virtual currency address at block 108, the sender or the physical currency receiver may use their sender device or physical currency receiver device 406 to create a multi-signature transaction that is configured to transfer virtual currency to the physical currency deliverer and that includes the system provider as a signing party, and sign and send a virtual currency transaction that is part of that multi-signature transaction.

One of skill in the art in possession of the present disclosure will recognize that the sender or the physical currency receiver may create the multi-signature transaction that identifies an amount of funds to transfer (which may be equal to the amount of physical currency being delivered and the fee specified by the physical currency deliverer for delivering the physical currency), identifies the physical currency deliverer as the destination of the funds, and includes the sender/physical currency receiver and the system provider as signing parties. For example, the multi-signature transaction created at block 108 may require signatures using both of a private key available to the sender or the physical currency receiver and a private key available to the system provider in order for that virtual currency transaction to transfer the identified funds from the sender or the physical currency receiver to the physical currency deliverer. As such, the sender device or physical currency receiver device 406 may gather (or generate) public ledger addresses, obtain public keys from the sender device or physical currency receiver device 406 and the system provider device(s) 402, and create a multi-signature transaction address for the multi-signature transaction. At block 108, the sender or physical currency receiver device may then create a virtual currency transaction that identifies the multi-signature transaction address as a destination of funds, and sign that transaction using a private key. As such, at block 108, the sender device or physical currency receiver device 406 provides information for signing the multi-signature transaction over the network 404 to the system provider device(s) 402.

In other embodiments, the system provider may generate a multi-signature transaction and send information for signing the multi-signature transaction through the network to the sender or the physical currency receiver. For example, the identification of the virtual currency address to the sender or the physical currency receiver at block 108 may be via a multi-signature transaction that is sent by the system provider to the sender or the physical currency receiver and that is configured to send virtual currency to that virtual currency address, as the system provider may use their system provider device 402 to create a multi-signature transaction similarly as described above, with the multi-signature transaction configured to transfer virtual currency to the physical currency deliverer and including the sender or physical currency receiver as a signing party. In response to receiving the information for signing the multi-signature transaction, the sender or the physical currency receiver may then sign the multi-signature transaction as discussed above.

In either of the embodiments discussed above (i.e., in which the sender or physical currency receiver creates and signs the multi-signature transaction and sends information for signing that multi-signature transaction to the system provider; or in which the system provider creates the multi-signature transaction, sends information for signing that multi-signature transaction to the sender or physical currency receiver, and the sender or physical currency receiver signs that multi-signature transaction), the system provider may then determine that the sender or physical currency receiver has signed the multi-signature transaction and, in response, confirm that the physical currency amount should be delivered to the recipient 412. For example, at block 108 the system provider may confirm that the sender or the physical currency receiver has signed the multi-signature transaction and, in response, use the system provider device(s) 402 to send a physical currency delivery confirmation through the network 404 to the sender device or the physical currency deliverer device 410. In addition, the system provider device(s) 402 may confirm the amount of physical currency, and the amount of virtual currency that will be transferred in the multi-signature transaction as well. In response to receiving the physical currency delivery confirmation from the system provider, the physical currency deliverer may then deliver the amount of physical currency to the recipient with the knowledge that the sender or physical currency receiver has committed to a virtual currency transaction (i.e., by signing the multi-signature transaction) that will reimburse the physical currency deliverer.

The method 100 then proceeds to block 110 where a reimbursement request code is received from the physical currency deliverer, and verified using the physical currency delivery confirmation code. In an embodiment, the system provider device(s) 402 operates at block 110 to receive a reimbursement request code through the network from the physical currency deliverer device 410, and verify that reimbursement request code using the physical currency delivery confirmation code that was generated and associated with the recipient 412 at block 106. For example, following receiving of the physical currency delivery confirmation, the physical currency deliverer may go to the recipient location, request and receive a code from the recipient 412, and use the physical currency deliverer device 410 to send a reimbursement request code (which is the code received from the recipient 412) over the network to the system provider device(s) 402.

Referring now to FIG. 11, an embodiment of a physical currency deliverer device 1100 is illustrated. The physical currency deliverer device 1100 includes a display screen 1102 displaying an embodiment of a physical currency code delivery verification screen 1104 that may be provided for display to receive a code from the recipient 412. In the illustrated example, the physical currency code delivery verification screen 1104 includes a code input section 1106 that instructs the recipient 412 to input the code provided to them by the system provider, the sender, or the physical currency receiver in order to receive the amount of physical currency sent by the sender. The physical currency code delivery verification screen 1104 also includes an input section 1108 that provides a virtual input device that may be utilized by the recipient 412 to input the code into the code input section 1106. One of skill in the art in possession of the present disclosure will recognize that the physical currency deliverer may also receive the code (e.g., audibly) from the recipient 412 and use the physical currency code delivery verification screen 1104 to input the code into the code input section 1106 as well. Upon inputting the code into the code input section 1106, at block 110 the physical currency deliverer device 410/1100 sends that code as a reimbursement request code over the network to the system provider device(s) 402. In an embodiment, the reimbursement request code may identify the recipient 412 as well.

In response to receiving the reimbursement request code through the network 404 from the physical currency receiver device 410, the system provider device(s) 402 operates at block 110 to verify the reimbursement code using the physical currency delivery confirmation code generated at block 106. For example, at block 110, the system provider device(s) 402 may compare the reimbursement request code received from the physical currency receiver to the physical currency delivery confirmation code that was associated with the recipient 412 and, in response to the reimbursement request code matching the physical currency delivery confirmation code, may verify the reimbursement request code and send a code confirmation notification over the network 404 to the physical currency receiver device 410. In response to receiving the code confirmation notification, the physical currency receiver may then provide the amount of physical currency identified in the physical currency transfer request to the recipient 412. As such, the physical currency deliverer may provide the physical currency to the recipient 412 in response to the recipient 412 providing the code that was generated by the system provider and associated with recipient 412 at block 106, thus assuring the physical currency deliverer that that recipient is the correct recipient for receiving the physical currency.

The method 100 then proceeds to block 112 where a multi-signature transaction that was previously signed by the sender/physical currency receiver is signed to cause a virtual currency amount to be transferred to the virtual currency address controlled by the physical currency deliverer. In an embodiment, the system provider device(s) 402 operates at block 112 to sign the multi-signature transaction discussed above to cause a virtual currency amount to be transferred to the virtual currency address that is controlled by the physical currency deliverer. For example, in response to verifying the reimbursement request code using the physical currency delivery confirmation code at block 110, the system provider may use the system provider device(s) 402 to sign the multi-signature transaction that, as discussed above, may have been generated by the system provider or the sender/physical currency receiver. As would be understood by one of skill in the art in possession of the present disclosure, the signing of the multi-signature transaction (which was previously signed by the sender or physical currency deliverer) by the system provider will cause that multi-signature transaction to be broadcast to the public ledger devices 414, confirmed by the public ledger devices 414, and added to the public ledger 418 such that the virtual currency amount specified in the multi-signature transaction is transferred to the virtual currency address controlled by the physical currency deliverer. As such, in some embodiments, as soon as the code received from the recipient by the physical currency deliverer is transmitted to the system provider and verified, the multi-signature transaction is signed so that the physical currency deliverer is immediately reimbursed for the amount of physical currency provided to the recipient, along with a fee for the physical currency delivery, using a virtual currency,

Thus, systems and methods have been described that provide for virtual currency secured physical currency transmissions by receiving a physical currency transfer request and, in response, identifying a physical currency receiver and a physical currency deliverer that may be verified/authenticated using a virtual currency public ledger. A physical currency delivery confirmation code is then associated with a recipient identified in the physical currency recipient information, and a virtual currency address that is controlled by the physical currency deliverer is identified to a sender or physical currency receiver. When a reimbursement request code is received from the physical currency deliverer, it is verified using the physical currency delivery confirmation code and, in response to the verification, a multi-signature transaction that has been previously signed by the sender or physical currency receiver is signed to cause a virtual currency amount to be transferred via the virtual currency public ledger to the virtual currency address that is controlled by the physical currency deliverer. As such, a virtual currency public ledger may be used to verify parties participating in the physical currency transmission system, and reimbursements for physical currency delivered to a recipient may be made via a multi-signature transaction that transfers virtual currency to the physical currency deliverer only when a physical currency delivery confirmation code is provided by the recipient in response to receiving the physical currency, thus securing the physical currency transmission using the virtual currency.

While the embodiments above discuss the delivery of a physical currency to the recipient during the method 100, in some embodiments, other instruments of value may be delivered to the recipient while remaining within the scope of the present disclosure. For example, instead of delivering a physical currency, the physical currency deliverer may instead generate, procure, purchase, and/or otherwise obtain a prepaid debit card that includes the amount of the physical currency provided by the sender, and may deliver that prepaid debit card to the recipient. As is known in the art, the recipient may then set up security features of the prepaid debit card such as a Personal Identification Number (PIN) and/or other authentication code so that the prepaid debit card may be used to make purchases. While a prepaid debit card has been provided as an example, one of skill in the art in possession of the present disclosure will recognize how a variety of other instruments of value may be utilized while remaining within the scope of the present disclosure as well.
